Answer:
32.46m/s
Explanation:
Hello,
To solve this exercise we must be clear that the ball moves with constant acceleration with the value of gravity = 9.81m / S ^ 2
A body that moves with constant acceleration means that it moves in "a uniformly accelerated motion", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.
When performing a mathematical demonstration, it is found that the equations that define this movement are the follow

Where
Vf = final speed
Vo = Initial speed
=7.3m/S
A = g=acceleration
=9.81m/s^2
X = displacement
=51m}
solving for Vf

the speed with the ball hits the ground is 32.46m/s
Answer:
There are four main types or classes of organic compounds that are found in all living things. These are carbohydrates, lipids, proteins, and nucleic acids. ... All organic compounds contain carbon, usually bonded to hydrogen. Other elements may also be present.
Explanation:
Melting: as mantle material rise toward the divergent plate boundary the pressure is reduced which causes melting
